Filed: 1987-04-23
Abstract: PURPOSE:To make it possible to dim regardless of the brightness of the external light by setting the brightness dimming value at the value of the maximum inner light brightness set value minus the measurement value of the external light brightness at the maximum dimming volume position, at the minus value of the external light brightness measurement value at the minimum dimming volume position, and at zero at the central position. CONSTITUTION:The external light voltage V0 output from an external light measuring device 1 at every point of time is turned back at the operation amplifier Q3 of a dimming circuit 7, and -V0 is fed to the Min side of the dimming volume VR2. On the other hand, the difference between the inner light maximum brightness set value Vimax and the voltage V0 is fed to the Max side, and the central position is grounded. The voltage V0, the voltage Vbeta of the volume VR2, and the output voltage Vi of an inner light measuring device 3 dim an inner light device 4 through an adder-subtractor 2 and an inner light controller 6. In such a composition, the maximum and the minimum inner light brightnesses are obtained at the Max position and the Min position of the dimming volume regardness of the brightness of the external light.

Abstract: PURPOSE:To curtail the number of signal lines connecting between an electric circuit device and a controller and the number of controllers, by providing a pulse generating means for adding one piece of pulse to the pulse and outputting them at a normal time, on plural pieces of electric circuit devices respectively. CONSTITUTION:When a check pulse is applied to a photosensor 11 of No.1 of the front stage, the photosensor 11 outputs two pieces of pulses and applies them to a photosensor 12 or No.2 at the normal time, and thereafter, the photosensors of No.2, No.3... output successively 3, 4... pieces of pulses and apply them to the photosensor of the following stage. In this state, if the photosensor of No.X becomes abnormal, this photosensor outputs only one piece of pulse, and X pieces of pulses are short, comparing with the normal time. In such a way, a count means of a controller 2 executes a count of N+1-X, and since the number of pulses is smaller by X than the count number N+1 at the normal time, it can be decided that the photosensor of No.X is abnormal.

Title: Releasing method of epoxy coating
Inventor: GOTO YUJI
IPC: H01L21/56
Filed: 1987-04-24
Abstract: PURPOSE:To clear the analysis of junction points, by a method wherein fuming nitric acid containing a specified amount of concentrated sulfuric acid is used as a releasing liquid to retard the dissolution of copper, and epoxy coating is released before copper is dissolved. CONSTITUTION:At the time of the internal analysis of a transistor, an epoxy coating is firstly released by applying fuming nitric acid. Instead of a releasing liquid of fuming nitric acid itself, a releasing liquid of fuming nitric acid mixed with concentrated sulfuric acid (98%) is used. The transistor is immersed in the releasing liquid and heated at 40-65 deg.C, the release reaction is enhanced. When the content of sulfuric acid is less than or equal to 5%, the effect to suppress the dissolution of copper is little, and when the content exceeds 20%, the damage of Al wiring of a pellet increases. The dissolution of copper is retarded, and release is enabled, without damaging junction points with parts so that the analysis is facilitated.
